Setting this option forces Android to stop each process as soon as it is empty (that is, when no services are started and no activities are on screen for that app). To be clear: this option won't stop apps that would normally run in the background from doing so. Your mail client will still run periodically to check mail, if it's configured to do that. Apps ...

I recently found that same setting (i.e., number of processes allowed to run in background), and I reduced that setting on my GT-S7562L from "Standard Limit" to only 1. I immediately saw a significant improvement in performance, and so far there have been no problems. I made the change out of desperation - my phone had nearly morphed into a brick. It was ...

Performance has nothing to do with battery voltage. The reason is that the flash memory is "worn" and therefore slower and less responsive. My Nexus 7 (1st generation) is also very slow now and I have almost no apps on it. You can read more here: Why Android Phones Slow Down Over Time, part "No Solid-State Drive TRIM" No Solid-State Drive TRIM The ...

Android supports fstrim but it only works if the phone is idle for a long time while charging It's not so. On newer versions, Android runs fstrim with a daily schedule, provided that the conditions meet. Or it should run on a reboot if not run for 3+ days. See this answer for details and how you can run fstrim manually. FRAGMENTATION ON FLASH MEMORY: I ...

There is an article that discusses the semi-technical reasons/issues that have lead to the differences in smoothness of Android and iPhone devices. But after gathering some key points from the article one can conclude: From the very start, IOS had been built around a multi-touch screen (meaning IOS had been built from the gound up to be very responsive ...

Assuming your lag is not caused by resource hogging malware (detection and removal covered in malware tag), possible causes (discounting infamous touchwiz :), could be CPU loading Disk I/O Network I/O RAM ( ignoring this going further given 3 GB RAM of your device ) Two apps would greatly help you in identifying the culprit system / downloaded apps ...

Is there any way of activating all cores? You can't. The hardware is not designed to have all 8 cores active. The reason for this is that this Octacore CPU is actually based on big.LITTLE technology, where there are two sets of four cores: a powerful big cores used for heavy processing (e.g. gaming) and energy efficient LITTLE cores used for low load ...

I understand that read/write speeds are dependent on what the phone is, and what the SD card is, but since both are flash memory, I thought the read/write times would pretty much be around the same. That is a wrong assumption. While they're all flash technology, there's a very wide certain in the speed of the storage. A Class 2 SD Card has a minimum read/...

Simple answer: Yes, but it's usually not noticeable and won't impact a device's ability to function as expected during it's lifetime. Full Explanation: Apps CAN leave traces of information behind when uninstalled. These are usually empty folder and misc. log files, but can also include files created by the application but are assumed that the user would ...

Because the devices that have hanging problems are not the ones with better processors and more RAM. Unlike iPhone, where there's only the expensive devices, Android runs on a whole range of devices. At one end, there are the flagships from the big manufacturers, which have a lot of effort put into them to make sure the animations are silky smooth and there ...

From the Android developer site: If an activity has lost focus but is still visible (that is, a new non-full-sized or transparent activity has focus on top of your activity), it is paused. A paused activity is completely alive (it maintains all state and member information and remains attached to the window manager), but can be killed by the system in ...

TL;DR: Get an A1 card unless you know for sure that your workload greatly benefits from Command Queuing (CQ) and your host hardware supports CQ. Long answer: After looking around a lot it seems that the A2 specification could allow better performance but actual hardware implementations are slow enough that A1 is better choice nowadays (year 2019).

I had the same issue. So, after a lot of work and tests, I've discovered that what was causing the issue was the Prey app. Do you have the Pray app (or similar) installed on your device, perhaps? After I've removed it, the dialer came back to work normally. Hope it helps.

The YouTube app has been and continues to be a laggy little dingleberry. Here are a few things to try: Is there the same level of lag when you try to load the video from youtube.com? Have you tried an alternative YouTube app like Viral? When updating to the latest nightly, do you clear your Dalvik cache?

The official Google Developers site has the full instructions and image repository on how to install a factory image for any Nexus device, including your "nakasi" Nexus 7 2012. I recommend 4.4.4, but you are free to go back as far as you want until you're comfortable with it's use. Cyanogenmod also has a stable 10.2 version (Android 4.3) - you can download ...

Phones use Solid State Drives (SSDs) for storage instead of traditional Hard Drives (HDDs). This is because carrying and jostling HDDs can cause hardware problems. Solid State Drives, however, get slow as you fill them up. So when you start to fill up your phone, its storage gets slower. This means that it takes longer to read the code from storage into ...

The problem is specialization! Apple's iOS is optimized for a small set of specialized Apple processors, which are ARM-based but because of e.g. custom extensions are able to do a lot more than the specification. Each app is compiled for every set of hardware (like one binary per CPU+GPU combination). Android needs to work on many different CPUs (Qualcomm, ...

I can answer you about TCP WINDOW SIZE and TCP WINDOWSCALE fields as they appear in the TCP header. Initial TCP Window Size should be 0x3908 = 14600, at least it is what I found so far using several versions. (On most Linux distro I've used it is exactly the double 0x7210 = 29200.) Window Scale has different values depending on the version, older set it ...

Android actually closes some background apps, but only when system ressources are missing (you open a massive game, for example) Greenify differ from the Android memory management by the fact that it kills all apps you specified at will or after a certain time, not only when ressources are missing. Nope. If some system apps that you do not use are ...

No, they are not installed on the device... Your device doesn't even "know" you purchased the app. It has absolutely no effect on your device at all and your purchase history is stored on Google servers, not your device itself. Your device has nothing to do with the "purchasing" of the application if you don't actually install it. You don't even need a ...

Your device is very old, which most likely means that it does not have exfat support. Compatibility should not be a problem, as every card and reader are usually compatible with each other, as long as SDXC cards are supported by your device. And for adoptable storage the bulk transfer speed is not that important (as long as you don't record videos or ...

Yes, when you see mmcqd on the top-3 processes most of the time you can assure there is a bottleneck created on any storage/flash. You can check that fact easily at the developer options in Android (how to get it), by enabling view CPU usage, the blue color represents I/O operations (more info). My scenario was more general than the one of the original ...

How to Speed up Slow Android Remember the day you bought your android? It wasn't slow. It was so fast. What happened? Did the silicon get slower? Did the bits get clogged? Of course not.

When the screen redraws, that is usually a sign of low memory. Considering this device is 3 years old, has 768mb of RAM, a 1GHz single core processor and running an Android version that was never even released for the phone, lag is going to happen. Chrome and Opera are both very memory hungry apps and since your device has a small amount of memory and an ...

In theory, your phone should perform considerably faster with CyanogenMod 11, because KitKat was designed with entry/mid-level phones in mind; requiring only 512 MB of RAM to run. (See this page about Project Svelte for more information.) CyanogenMod also adds a whole slew of features like Heads Up Notifications and Privacy Guard on top of the AOSP code, so ...

According to Wikipedia: High Speed Packet Access and Evolved HPSA, HSPA+ has a theoretical maximum download of 84 Mbps and an upload of 10.8 Mbps. Using Dual Cell Technology, it can be doubled to 168 Mbps download and 22 Mbps upload. This suggests that the upload speed will not be anywhere close to the download speed. Doing a search for HSPA+ 21 Mbps, most ...

First I would jump into the developer options and play around with rendering settings in there. This is going to pertain to the GPU probably a lot more than the CPU. You can also enable some helpful rendering overlays to get visual feedback regarding touch areas, rendered areas, and gpu utilization. Unfortunately I can't say that one particular item or ...
